Proto-Sound 3.0 features are activated by sequences of Bell and Horn button pushes
described below. Please read the full descriptions of each feature before using it. To
use these buttons to activate features rather than to blow the horn or ring the bell,
you should tap the buttons very quickly with a ½-second pause between button
presses. You may need to practice your timing to make this work smoothly.
